Title: Apparatus for testing the pressure inside a closed container
Inventor: SOLOMIDES LOUIS ZENON
IPC: G01M3/36
Filed: 1963-03-12
Abstract: 1,037,533. Pressure testing using sound waves. LONDEX Ltd. Jan. 20, 1964 [March 12, 1963], No. 9727/63. Heading H4D. The pressure difference across a flexible wall portion of a closed container is determined by setting the wall portion in vibration and detecting the amplitude or frequency of the resulting vibration. The invention is applied to the detection and rejection of jars of fruit 12, Fig. 1, provided with metal cap 12a, which have an imperfect vacuum. The testing head means 11 for setting the cap 12a into vibration, comprises a coil 15 energized from a variablefrequency source 19 to induce currents in the cap, and a permanent magnet 16 producing a magnetic field coacting with the induced currents and causing the cap to vibrate. A microphone 18 surrounded by sound insulating material 17 detects the amplitude of the resulting sound waves and feeds a signal to a variable sensitivity receiver 23, which produces a signal to reject the jar when a sound amplitude is detected indicating a poor vacuum. The testing heads 11 may be arranged in groups of six around the edge of a rotating mounting 31, Fig. 2 (not shown), with the jars being passed beneath the rotating heads on a conveyer belt 13, Fig. 4 (not shown), a star wheel 41 guiding each jar into alignment with a respective testing head. The faulty jars are rejected along a conveyer belt 44. A stationary plate 39, Fig. 2 (not shown), carries a printed circuit oscillator and receiver amplifier, whilst a rotating plate 38 carries a printed circuit commutator for connecting each testing head to the oscillator and amplifier in turn. The output of the oscillator 19 may be continuous or pulsed or frequencymodulated to seek and possibly track by positive feedback means, the resonant frequency of the cap. The signal from the microphone can be passed through filter means to increase selectivity, or it may be added in antiphase to a constant reference signal whereby a resultant signal differing from zero indicates a good vacuum. To minimize the effects of extraneous noise the microphone output can be switched at a rate of 100 times a second from one circuit to another and the two circuit signals recombined, after rectification and smoothing, in antiphase, whereby the average noise component is reduced to zero. The switching means which may be of the semi-conductor kind, may cause the energizing of the coil 15 on alternate onehundredths of a second only, such that the vibration signal is only present in one of the above two circuits and can produce a rising output voltage on detection of a faulty container.

Title: Improvements in methods and devices for grinding cooperating faces of friction members
IPC: B24B7/10
Filed: 1940-06-04
Abstract: 573,926. Grinding friction surfaces. COTAL, J. June 4, 1940, No. 9779. Convention date, June 24, 1939. [Class 60] Co-operating friction-members such as are used'in magnetic clutches are ground together, and thereby hardened, by the following method. The members, after being separated, are driven at different absolute speeds ; next, one member is allowed to rotate freely, and the members are then held in close contact until they rotate at the same absolute speed. Pairs of friction-members consisting of a disc 8 and an armature 9 are mounted on shafts 11 in a casing 12a, gears 7, 13 on the members co-operating with a gear 6 on a shaft 5, and a stationary gear 14 respectively. The shaft 5 can be coupled by a magnetic clutch 1, 4 to the shaft of a motor 3. A rotary commutator 23 is arranged to energize alternately the clutch 4 and the armatures 9, thereby causing the members 8 to be driven, and the armatures forced into contact therewith in alternation. After a number of operations, the pairs of members 8, 9 are removed. A pump 15 supplies lubricant to the hubs of the members 4, 9. In a modified apparatus for grinding the members 34, 39, 37, Fig. 3, of a variable-speed gear, comprising a driven shaft 42 provided with planet-wheels cooperating with annuli 36, 40 on the members 34, 39, the member 34 is driven through a magnetic clutch 1, 4 by the driving-shaft 2 of the apparatus, and the member 37 is secured to the casing 12a. The members 34, 37 are provided with electromagnets which are energized alternately under control of a rotary commutator 23 to drive or lock the member 39 and thereby effect the grinding of the working faces.

Abstract: 218,399. O'Shaughnessy, F. R. March 27, 1923. Drawings to Specification. Right to Patent relinquished. Aerating.-The bulk of the solid faecal matters are removed from sewage and the liquid is then aerated in the presence of two to ten per cent of flocculated sludge. The sludge which separates on settlement is aerated by itself before being used in the treatment of further liquid. For this separate treatment the concentration of the sludge should be below 35 per cent for temperatures below 10‹ C. and above 15‹ C., and below 40 per cent for temperatures between 10‹ and 15‹ C., the concentration being measured by the ratio of the volume of the settled matter to the total volume after standing for eighteen hours. Flocculated sludge for the initial treatment is prepared in the usual manner by aeration treatment of sewage from which the solid matters have been removed.

IPC: H01M8/02
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To prevent the vanishment of a fuel cell electrolyte without lowering fuel cell power generating efficiency, by arranging an auxiliary fuel cell, having capacity smaller than that of a fuel cell main body, in the upstream part of an oxidant gas flow passage to the fuel cell main body separately from the fuel cell main body, to supply an oxidant gas to the fuel cell main body. SOLUTION: An auxiliary fuel cell 1 is provided in the upstream part of a flow passage for supplying an oxidant gas to a fuel cell 2 separately from a fuel cell 2 main body, to supply the oxidant gas to the fuel cell 2 via the auxiliary fuel cell 1. Here, in air to be used as the oxidant gas, part of oxygen is consumed for power generation by the single cell 7 of the auxiliary fuel cell, and phosphoric acid vaporized from the cell 7 is mixed into the oxidant gas in a condition near to saturation vapor pressure, to be supplied to the fuel cell 2. Consequently, electrolyte evaporation into the oxidant gas is restrained in the fuel cell 2, thereby causing no shortage of an electrolyte in the fuel cell 2 even in 40000 hours continuous operation to ensure safe operation.
